This conference served as a platform to bring together Purdue students and faculty to discuss how light-based technologies could help address the grand challenges facing our society such as providing affordable solar energy, personalized medicine, etc. The talks are by Graduate students and...

n this talk, I will describe optical techniques that can measure the magnitude and direction of spin-orbit fields and electrically-generated spin polarization in non-magnetic semiconductors and the modification of the electron spin precession frequency in a bulk semiconductor using an applied...

In this talk, I will discuss our recent efforts on elucidating multi-scale energy transfer, migration, and dissipation processes with simultaneous femtosecond temporal resolution and nanometer spatial resolution. We have combined/correlated ultrafast spectroscopy with high spatial resolution...

In this lecture I will begin with a brief introduction to ultrafast optics and specifically to methods permitting shaping of ultrafast laser fields on time scales too fast for direct electronic control. For contrast I will first provide some brief perspective on the state of my research around...

This talk will begin with a brief general introduction into ultrafast optics and then specifically address the topic of shaping ultrafast laser fields. Because the time scales involved are much too fast for direct application of (opto)electronic modulator technologies, all-optical approaches are...

Plasmonics has gained significant attention in the recent days owing to its capability of providing sub-wavelength confinement of light. As a consequence of sub-wavelength confinement of electric field, the field intensity issignificantly enhanced. High field intensity achieved by plasmonics,...

Dual comb spectroscopy is introduced, a technique that is basedon the beating of two frequency combs. A sample is first interrogated bythe combs before they are beat together via photodiode which down convertsthe signal from the optical to RF domain where it can be processed with electronics. A...
